High-Temperature Magnets for AI Hardware and Robotics

Artificial Intelligence (AI) is not just software – it relies heavily on advanced hardware. Training large AI models requires powerful chips, cooling systems, robotics and precision instruments. In all of these fields, magnets are key components.

Standard Neodymium magnets lose their strength at around 80°C, which is not enough for demanding AI hardware. Inside motors, actuators, cooling pumps, and precision sensors, the temperature can rise far beyond that limit. This is where high-temperature magnets become essential.

Neodymium High-Temperature Grades (SH, UH, EH, AH)

Neodymium magnets are unmatched in strength, but for AI applications special heat-resistant grades are used:

• SH up to 150°C
• UH up to 180°C
• EH up to 200°C
• AH up to 220–230°C

These are widely used in:

• Robotics motors and actuators
• Pumps for liquid cooling systems
• Magnetic sensors in power supplies

Samarium-Cobalt (SmCo) – the Premium Choice

For even harsher conditions, Samarium-Cobalt magnets are the gold standard. They withstand up to 350°C, resist corrosion and deliver stable performance over time.

Common applications include:

• High-performance servo motors
• Precision instruments in research
• High-temperature sensing equipment

AlNiCo – Reliable in Extreme Heat

AlNiCo magnets are not as strong as Neodymium or SmCo, but they can resist up to 500°C. That makes them highly valuable in:

• Magnetic stirrers in laboratories
• Measuring and testing devices
• Specialized electric motors

Ferrite – Affordable and Robust

Ferrite magnets are cost-effective, corrosion-resistant and stable up to 200°C. They play an important role in:

• Transformers and power electronics
• Speakers used in AI systems
• Magnetic couplings in pumps

Conclusion

The rise of Artificial Intelligence drives a massive demand for hardware innovation. From robotics to cooling systems, high-temperature magnets are essential for reliable performance.

Whether Neodymium SH–AH, Samarium-Cobalt, AlNiCo, or Ferrite – each material offers unique advantages for AI-driven technology.
